Source Description
UniProtTranscription factor. Plays a crucial role in tapetum development. Required for male fertility and pollen differentiation, especially during the post-meiotic transcriptional regulation of microspore development within the developing anther (PubMed:12535353). Binds E-box regions in the AHL16/TEK promoter. {ECO:0000269|PubMed:12535353, ECO:0000269|PubMed:24804694}.
